Inefficient conversion of nitrogen oxides and particulate matter during transient engine states. Reducing these emissions ensures compliance with environmental regulations and prevents environmental degradation.

Imprecise control over residual gas levels leads to unstable combustion and increased emissions. Accurate charge management improves thermal efficiency and engine stability.

Excessive pressure or vacuum within the crankcase leads to seal failure and oil degradation. Proper regulation prevents atmospheric contamination and engine damage.

Toxic exhaust constituents and unreacted propellants pose environmental and safety risks. Reducing these pollutants ensures regulatory compliance and improves chemical conversion efficiency.
